SAFETY DEVICE FOR JEWELRY.

SPECIFICATION forming part of Letters Patent No. 527,358, dated October9, 1894.

Application filed April 5, 1894- Serial No. 606,455- (No model.)

To all whom it may concern.-

Be it known that I, JULIUS BONNER, a citizen of the United States,residing at New York, 1n the county and State of New York, have luventednew and useful Improvements in Looks for Ear-Wires, Scarf-Pins, andSimilar Articles, of which the following is a specification.

This invention relates to a simple and effective device by means ofwhich an ear ring,

a scarf pin, a lace pin or another article of a similar nature can besecured in the required positlon sothat it cannot become detached eitherby accident or by design.

The peculiar and novel construction of my lock is pointed out in thefollowing specification and claims and illustrated in the accompanyingdrawings, in which Flgure 1 is a side elevation of an ear wire provldedwith my lock, the lock being shown 1n section along the line 00 a: Fig.2. Fig. 2 is a transverse section in the plane y y Fig. 1. Flg. 3 1s asimilar .viewwhen the lock is open. Fig. 4. is a side elevation of ascarf pin provided with my lock.

In the drawings the letter A designates the shank of the ear wire or pinto which is secured the setting Bin any desirable manner. Said shank isprovided with recesses 10 which may extend clear around or onlypartially round the shank.

C is the lock which I have constructed for the purpose of retaining thepin in the required position. This lock consists of a plate 11 which isprovided so that it can be readily applied to the shank A and easilymoved thereon into the required when the position. On this socket plate11 is movably secured a catch 14. so that when the socket plate has beenmoved into the required position on the shank A, said catch can bebrought into engagement with one or more of the recesses 10 in theshank.

' In the drawings the catch 1418111 the form which form portions ofconcentric circles described from the center of the pivot 15 so thatcatch is moved in a plane parallel with a socket or hole 12 with thesurface of the plate 11 to the position shown in Figs. 1 and 2, the slot16 engages one of the recesses 10 in the shank A so as to lock thesocket plate in the required position, and when thecatchis moved to theposition shown in Fig. 3, the socket plate 11 is released so that it canfreely move in or out on the shank A. Furthermore the recesses 10 in theshank A are made circular and the ridges between the adjoining recesseshave sharp edges and the edges of the slot 16 are also chamfered 011 toform sharp edges (see Figs. 1 and 4.) so that when the catch "14 isturned to its locking position, the edges of its slot will readily findtheir way into one of the recesses 10. From the socket plate 11 extendsa finger piece 17 and a similar finger piece 18 extends from the catch14. By means of these finger pieces the catch 14. can be readily thrownin or out of engagement with the recesses 10 in the shank A and when mylock is applied to an ear wire or to a lace pin which in their normaluse occupy a horizontal or approximately horizontal position, the fingerpieces 17, 18, cause thelock to gravitate to the position shown in Figs.1 and 2, so that it cannot become disengaged by accident.

What I claim as new, and desire to secure a by Letters Patent, is-- 1.The combination with a shank A having recesses 10, of a plate 11 havinga socket 12 fitting and adjustable along the length of the shank, and acatch carried by the socketed plate and movable thereupon in aplaneparallel with the surface of the said socketed plate to engage anddisengage the recessesin the shank, substantially as described.

2. The combination with a shank A having recesses 10, of a plate 11having a socket 12 loosely fitting and adjustable along the length ofthe shank, and a catch-plate let pivoted to the socketed plate andoscillating thereupon in a plane parallel with the surface of saidsocketed plate to engage and disengage the recesses 10, of a plate 11loosely fitting and adjustable along the length of the shank, and acatch-plate pivoted to the socketed plate 5 of a disk or plate securedto the socket plate recesses in the shank, substantially as de- 5 11 bymeans of a pivot 15 and in the catch scribed. 1 is formed a segmentalslot 16, the edges of 3. The combination with a shankA having andoscillating thereupon in a plane parallel with the surface .of the saidsocketed plate, 7 said catch-plate having a se,g ;1:11e1 11;a1 slot,theedges of which are approximately concentric 5 with the pivot of thecatch-p1ate, subsj;an-

tially as and for the purposes described.

In testimony whereof I have hereunto setv my hand in the presence of twosubscribing Witnesses.

JULIUS BONNER.
